Digital Timer counts down from the time you set. When the cycle is completed, a very loud 103dB warbling buzzer sounds and the illuminated button lights up. Resets automatically to the same time for the next cycle. Easy to program with only three pushbuttons.

Many different possible operating modes are selectable with switches inside the box. You can control if a cycle is able to be cancelled or not, automatic cycle end or manual, timing in HH:MM or HH:MM, relay orientation, repeating cycles, guard duty. See details in the instructions below.

Waterproof, corrosion-proof IP65 (NEMA 4X) enclosure is built for plating lines, commerical kitchens, factories, wet or corrosive environments., indoors or out.


Easy to set the time: the blue buttons adjust the time up or down. The large green button starts and stops the time cycle, or cancels a cycle if permitted by the mode.


  • A beacon LED give the timer very high visiblity if needed.
  • Magnetic feet allow the timer to be mounted on steel surfaces like the front of an oven.
  • Different buzzer tones so different timers can be distinguised audibly.
  • Volume control allows contiuously variable volume.

The Loudest Buzzer

This is the loudest buzzer we know of on a digital timer. Be cautious of volume ratings from other manufactuers as they may give a high volume number but this is meaningless without knowing the distance! more info
